FEATURES One half bridge for 7.4A load (ron = 150mΩ) Two half bridges for 5A load (ron = 200mΩ) Two highside drivers for 1.25A load (ron = 800 mΩ) Programmable Softstart function to drive loads
with higher inrush currents (i.e.current >7.4A,
>5A, >1.25A) Very low current consumption in standby mode
(IS < 3µA, typ. T j ≤ 85 °C) All outputs short circuit protected Current monitor output for all highside drivers All outputs over temperature protected Open load diagnostic for all outputs Overload diagnostic for all outputs Programmable PWM control of all outputs Charge Pump output for reverse polarity
protection
APPLICATION Rear Door Actuator Driver with bridges for door
lock and safe lock and two 5W or 10W-light
bulbs.
DESCRIPTIONThe L9951 is a microcontroller driven multifunc-
tional rear door actuator driver for automotive ap-
plications. Up to two DC motors and two grounded
resistive loads can be driven with three half bridg-
es and two highside drivers. The integrated stan-
dard serial peripheral interface (SPI) controls all
operation modes (forward, reverse, brake and
high impedance). All diagnostic informations are
available via SPI.
